Jay Momaya

Fullstack engineer · Mumbai, India

Fullstack engineer in Mumbai, India. Nine and a half years of shipping software, from PHP at Solution Planets in 2017 to Technical Lead at Calsoft today.

Most of that time went into systems a business runs on: an ERP that every department of a publisher worked in, the seminar-to-sale pipeline for Sharekhan, exam prep that kept students studying through Covid. Since 2023 it’s been Gen AI — QuickAction, Call AI, and EHCP drafting that gets UK council plans out in a fraction of the time.

I work the whole stack because most of the interesting problems live between the layers: the schema that makes the query fast, the API shape that makes the UI simple, the eval that tells you whether the model actually helped.

On my own time I build iPhone apps. LoveLapse is live on the App Store, Pulseboard is in review and Tijori is in TestFlight. All three keep your data on the phone.

Off work, it’s mountains: thirteen treks and hikes since 2020, from Sahyadri forts and waterfalls to Hampta Pass and Komic, 15,049 ft, in Spiti Valley. Annapurna Base Camp and Kedarkantha are next. In 2026 I spent seven months on fat loss — 75 kg to 66 kg, 33% to 23% body fat — and I photograph all of it on an iPhone.

Freelance, remote or Mumbai, around twenty hours a week, and I’ll work to your time zone. I take on a small number of projects so each one gets real attention.
